Standard Gibbs energies of transfer of halogenate and pseudohalogenate ions, halogen substituted acetates, and cycloalkyl carboxylate anions at the water|nitrobenzene interface

The previously introduced three-phase electrode technique was used to determine the Gibbs energies of transfer of ClO3 , BrO3 , IO3 , IO4 , OCN , SeCN , CN , N3 , halogen substituted acetate anions Z3 nCHnCOO (Z 1⁄4 F,Cl,Br,I), and cycloalkyl carboxylate anions ((CH2)nCOO , n 1⁄4 3,. . .,7) at the water|nitrobenzene interface. Whereas the data for the small inorganic ions can easily be understood in terms of ion-dipole interactions, the data of the organic ions need consideration of charge delocalisation and its effect on the enthalpy and entropy of solvation.
